摘要： A method for fabricating semiconductor devices comprising the steps of: forming on the main surface of a semiconductor substrate an inorganic photoresist layer having a first amorphous layer, which contains Se as a matrix component and includes an impurity for providing one conductivity type and a second silver, or a silver containing layer, formed on the first layer; exposing the inorganic photoresist layer with an exposure pattern; developing the exposed inorganic photoresist layer to form a patterned impurity containing inorganic photoresist layer as an impurity source layer; forming a heat resistive overcoating layer on the main surface of the semiconductor substrate, while covering the impurity source layer; and forming a doped region by diffusing impurity from the impurity source layer into a region of the substrate underlying the impurity source layer. The heat resistive overcoating layer may be an insulation layer having a window through which a conductive layer is connected to the doped region and is extended over the overcoating layer. The doped region is formed readily and accurately with relatively few process steps and with a pattern corresponding to an exposure pattern for the inorganic photoresist layer. The diffusion of the impurity from the impurity source layer into the substrate is accurately controlled so as to provide the doped region with a desired impurity concentration. Moreover, the evaporation of the impurity into the atmosphere during processing is minimized.

摘要： An optical disk drive includes: an objective lens for converging a light beam onto an optical disk with an information storage layer; an actuator for moving the lens perpendicularly to the storage layer; an actuator driver for moving the lens at a predetermined velocity by controlling the actuator's operation; and a disk position detector for detecting the position of the lens, when the focal point of the beam is located on the storage layer, as a disk position. While the lens is being moved toward the disk to perform a focus finding operation, the moving velocity of the lens is set high until the lens reaches a velocity switching point, determined by reference to the disk position, and is set low once the lens has passed the point. The switching point is set farther away from the disk than the position of the lens is when the focal point of the beam is located on the storage layer of the disk.

摘要： An optical disc drive according to the present invention can write data on both a write-once disc and a rewritable disc. The drive includes: a disc recognizing section 110 for recognizing the type of a given optical disc as a write-once disc or a rewritable disc; and track skipping detection signal generating section, which outputs track skipping detection signal when a first condition on tracking error is satisfied if the given optical disc, on which data is being written, has turned out to be a write-once disc. On the other hand, if the given optical disc has turned out to be a rewritable disc, the track skipping detection signal generating section outputs track skipping detection signal when a second condition on tracking error, which is different from the first condition, is satisfied. A control section stops writing the data in response to the track skipping detection signal while the data is being written.

摘要： An optical disc apparatus includes: a defect detecting section 124 for detecting, based on a light detection signal and with respect to a preset detection reference level, a fingerprint or a bubble on the disc 102 as a defect to output a defect detection signal; and a waveform shaping section 126 to output a hold signal that holds, in response to the defect detection signal, a signal from a tracking control section 109 at a level just before the defect has occurred. The apparatus is initially operated not to hold the signal from the tracking control section 109 even if there is a defect. But once a tracking failure has occurred during a read operation, settings are changed to hold the signal from the tracking control section 109 against the defect while the read operation is retried.

摘要： An optical disk apparatus is provided with an actuator that moves a beam spot that is formed by an optical head on an optical disk to recording surfaces; position control portions that control a position of the beam spot based on the output signal of the optical head; a disturbance estimation observer relating to the actuator; and a summing circuit that takes a sum of the output of the position control portion and the output of the observer, so as to drive the actuator based on the output of the summing circuit. The optical disk apparatus further is provided with a system controller that turns the observer on and off, a LPF that attenuates the high-frequency components of the output of the observer and retains the final value of the observer when the observer is turned off, and a switching circuit that switches between the output of the observer and the output of the LPF according to whether the observer is on or off. When the observer processing is off, the output of the LPF is supplied to the summing circuit. Thereby, instability in the control due to observer processing can be avoided even at the time of mode transition or addition of disturbance from outside.
